[NSFW] Server Error o some pages.

Hello,

I just got a server error when calling up the contest evaluation.
Also the display of thumbs of an album: when I select the view Basic – Thumbs and NOT the TYPE “Masonry xxx” in Thumbs III:layout #1. doesn’t work.

The existing pages with contest results do not work and new pages with results cannot be created.

I get the following error message from WordPress:

Is this a WPPA problem? The website has not been changed in principle, except for the current competition.
